Application filed October 9, 1915. Serial No. 54,968.

Fig. turn;

Fig. '16 is a section on the line 6-4) Fig. 12.

Difiiculty has always attended the use of miter corner sections, first on accbunt both of the obstruction presented by the right angle turn, and further by the miter joint breaking down where the parts become separated. I have experimented for a number of years to produce the corner turn or miter section for gutters disclosed in my present application. It has denier: firated its efiiciency for strength and durability and also its capability ofdeflection to prevent backing of either wateror debris at the corner or turn. 7

Referring to the completed gutter turn, 2 refers generally a the unit structure. 3 and lare sections disposed relatively at right angles, which conform in bearing and in size to line gutter sections. 5 refers to the turn portion of the complete section. the same being extended to a greater width than sections 3 and 4c. 6. refers to the inner turn (if the gutter and practically necessarily unrolled or flanged. 7 refers t rolled or tubular outer and upper edge portion of the gutter, which as will. hereinafter be enplained, being formed from a flanged memher out at spaced intervals downwardly from a line conforming to a horizontal plane slightly below the center of the corner turn portion 8 of said rolled or tubular member 7, said out members being caused to overlie and when properly rolled assume conical form and interlock to form a continuation of-the tubular edge member 7 having the same rigidity and strength as the uncut edges of said rolled edge. The outer extremities of the rollededge member are cut away as at 9 to facilitate entrance of line gutter members.

The article produced by the above operations has the advantage that the curvature at its outer edge portion prevents the lodgment of sediment and debris, and also serves to deflect the water flowing through the gutter. .A new result is obtained inthe formation of gutter turns, in that by the steps employed to modify the forms'progressively, ample material is afforded to draw from and the strain in drawing is so distributed that the integrality of the metal is preserved so that the article as finally produced is not jwcak 15 is a detail edge View of the corner ened or broken, and surplus material result ing from the pressing action is effectually reduced to the plane of the surface of 't e gutter so that no obstructions whatever ap pear at the turn.

What I claim is:

1. As a new article of manufacture, a corner turn for gutters formed from a single sheet of metal having an unbroken and unobstructed interior surface, an integral outer rolled or tubular edge member, the turned portion of said tubular edge member beingcut to form separate units and pressed into conical overlying impinging portions of the corner turn.

2. As a new article of manufacture, a corner turn for gutters formed from a single sheet of metal having an unbroken and un obstructed interior surface, its line members depressed relatively at right angles and its corner portions curved upon conformatory lines throughout the body of said corner turn, and an integral outer rolled or tubular edge member.

3. As a new article of manufacture, a corner turn for gutters formed from a single sheet of metal having an unbroken and unobstructed interior surface, its line members depressed relatively at right angles and its corner portions expanded on cross sectional lines a greater Width than that of the line members and curved upon conformatory lines throughout the body of said corner turn, and an integral. outer rolled or tubular edge member. the turned portion thereof being cut to form separate units and pressed into conical overlying impinging portions of the corner turn.

4; As a new article of manufacture, a corner turn for gutters formed from a single sheet of metal having an unbroken and unobstructed interior surface, its line members depressed relatively at right angles and its corner portions expanded on cross sectional lines a greater Width than that of the line members and curved upon conformatory lines throughout the body of said corner turn, and an integral outer rolled or tubular edge member, the turned portion thereof being cut from its edge to a line conformatory with a plane substantially through the horizontal center of the tubular edge member.

In testimony whereof I have affixed my signature in presence of two Witnesses.
